Title: Preparation of crosslinked high density polyethylene foam
Inventor: OGAWA TOKUJI
IPC: C08J9/04
Filed: 1977-10-31
Abstract: PURPOSE: To prepare a uniformly and highly foamed closed-cell crosslinked polyethylene molded article, having higt heat resistance, economically, by irradiating a polyethylene molded article containing a low molecular weight compound and an organic peroxide with ultra-violet ray thereby crosslinking the article, and impregnating the crosslinked article with an evaporation-type foaming agent followed by heating and foaming thereof.  
     CONSTITUTION: An organic peroxide is added to a resin composition composed of (A) 75W40wt% of high density polyethylene, (B) 20W5wt% of a low molecular weight compound miscible with said polyethylene resin, and having an average molecular weight of 300W5000, e.g. paraffin wax, polybutene, polyethylene wax, etc., and (C) 5W55wt% of low density polyethylene, and the mixture is kneaded and molded. The molded article is crosolinked by irradiating with ultra-violet ray at a temperature above the melting point of the high density polyethylene and at temperature and time conditions under which the foaming of the article does not occur without the UV-irradiation. After the crosslinking, the article is impregnated with a normally gaseous evaporation-type foaming agent under high temperature and pressure, and foamed by heating.

Title: Waterproof casing
Inventor: HONMA TOMOYUKI
IPC: H05K5/02
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To secure the air permeability, and prevent the entrance of insects crawling up to a fine-pore sheet, by covering a sheet, which does not pass water though the breath hole provided in one flank has air permeability, with a netlike cap made of metal or plastic. SOLUTION: The bottom 2 of a waterproof casing 1 is provided with a recess 3, and a breath hole 4 is made within this recess 4. A fine-pore sheet 5 of such material that it has permeability but does not pass water is arranged outside the breath hole 4 made in the recess 3. Furthermore the fine-pore sheet 5 is fixed outside of it, and also metallic net 6 for protecting the fine-pore sheet 5 from the penetration of insects is fixed to the recess 3 of the waterproof casing 1 with screws 7. The metallic net 6 has a projection 6a with roughly the same diameter as the breath hole 4, and is fixed to the casing 1, being positioned to the breath hole 5, so as to secure a passage of air to the fine-pore sheet 5.  By the breath hole structure consisting of the breath hole 4, the fine- pore sheet 5, and the metallic net 6, the pressure within the casing 1 and the outside air pressure are kept equally while securing the passage of air into the casing 1 and securing the permeability of the casing 1.

Title: Transfer device and device for manufacturing semiconductor
Inventor: KISHI FUMIO
IPC: B65H5/00
Filed: 1987-05-28
Abstract: PURPOSE:To convey a transfer base in a dust-free state or in a vacuum by placing the transfer base having a magnet on a transfer passage including a superconductor, and levitating the base by a repelling force due to Meissner effect. CONSTITUTION:When a chucking electromagnet 8 under a superconductor 6 is energized, its magnetic field exceeds the critical magnetic field of the superconductor 6 in a transfer passage 9, its superconducting state is broken, and a transfer base 2 loses its levitating force, and attracted to the surface of a thin stainless steel plate 4 by the magnetic field generated from the electromagnet 8. When the base 2 is moved, the magnetic flux of a permanent magnet 3 buried in the base 2 is first detected by a Hall element 11 to detect the position of the base 2, an electromagnet 10 is suitably energized in response to the position detection signal to move the base 2. Thus, since it uses neither gas nor mechanical driver, it can be transferred in a dust-free state or in a vacuum.

Title: Surface acoustic wave device and its manufacture
Inventor: MORIKOSHI HIROKI
IPC: C30B29/32
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain a surface acoustic wave device with a small loss by forming an electrode to stimulate, receive or reflect a surface acoustic wave to the surface of a perovskite ferroelectric single crystal film including lead. SOLUTION: Interdigital electrodes 3, 5 are formed to the surface of the perovskite ferroelectric single crystal film 2 including lead. An electric signal fed to the stimulation side interdigital electrode 3 is transduced into a surface acoustic wave 4, the surface acoustic wave 4 is propagated in the ferroelectric single crystal film 2 and the wave 4 is transduced again into an electric signal by the receiver side interdigital electrode 5. Since the ferroelectric single crystal film 2 of a homogeneous material is used for a part where the surface acoustic wave 4 is propagated, scattering of the surface acoustic wave 4 propagated in the film is reduced and the loss of the surface acoustic wave device is reduced.  Furthermore, it is required to select a film thickness of the ferroelectric single crystal film 2 to be a wavelength of the surface acoustic wave 4 or over to propagate the surface acoustic wave 4 without being affected by the single crystal substrate 1.

Title: Preparation of liquid absorbent for carbon monoxide
Inventor: KUWABARA TAKANORI
IPC: C01B32/40
Filed: 1982-07-29
Abstract: PURPOSE:To prepare an absorbent liquid having high water resistance while maintaining absorption performance by using the adsorbent liquid of CuCl-tris (dimethylamino)phosphine oxide (HMPA)/toluene, and changing the amt. of HMPA and other solvents according to the moisture content in the gas to be treated. CONSTITUTION:It is preferred to maintain the concn. of CuCl in an absorbent liquid at 1.0-2.0mol/l, more preferably 1.5-2.0mol/l to maintain the amt. of CO to be absorbed in the absorbent liquid at a practicale value, and CuCl is dissolved in HMPA to form a CuCl-HmPA complex for said purpose. If the concn. is increased in order to improve water resistance, the viscosity increases and the absorption rate of CO decreases. Therefore, for example, toluene is further added as a low viscosity solvent to the soln. of CuCl-HMPA complex to adjust the viscosity. The parts shown by horizontal lines are the range where precipitate, that is, CuCl(S) is not formed, which covers a range where the water resistance is higher as the ratio of HMPA with respect to CuCl is higher.
